Plastic Injection Molding

The plastic injection molding is the most common method of part manufacturing. It’s a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or engineer, molds are made by a moldmaker from metal, usually either steel or aluminum, and precision-machined to form the features of the desired part. It is widely used for manufacturing a variety of parts. We are able to provide a one-package service, including design, mold making, plastic injection molding, painting, assembly, packaging, and delivery.
